[Change in cerebral microcirculation at long-term periods following irradiation with protection by gammaphos].

A study was made of the influence of prophylactic administration of gammaphos (300 mg/kg) on radiation alterations in the system of cerebral microcirculation of rats in a long-term period following local irradiation of doses of 40-60 Gy. It has been shown that the number of animals with severe vascular injuries and the degree of these injuries lessen. A computerized analysis has shown that gammaphos administration weakens a decrease in the mean number of vessels and an increase in their average size caused by irradiation.
